Abigail L. ★★★★★ Oct 23, 2026

Heavy enough to keep my tablet mount rock solid while driving, and the aluminum feels like it will last for years. The 9x9 surface gave me plenty of room to bolt down my setup without any wobble. Really pleased with how stable it is.

The AMPS hole pattern lined up perfectly with my existing mount, saving me from drilling extra holes. The aluminum feels solid enough to keep my tablet steady during bumpy drives, and the 9-inch footprint fits nicely on my workbench.

It was heavier than I expected for its size, which gives me confidence it won't slide around on my desk. The AMPS pattern let me attach my existing monitor arm without any drilling or hassle.
